Drug inspection device

A medicament inspection device comprising:

• an inspection section where a medicament enclosed in a package is placed;
• an illuminating device for illuminating the package placed in the inspection section;
• a camera device for taking images of the package placed in the inspection section and illuminated by the illuminating device;
• and
• a control device for executing a medicament information detection process to detect a number and/or a type of the medicament enclosed in the package, as medicament information, by performing an image matching process using the images taken by the camera device;
• wherein the illuminating device comprises:
• a front side illuminating device for illuminating the package from a side where the camera device is located, and
• a back side illuminating device for illuminating the package from a side opposite to the camera device;
• wherein the images taken by the camera device include:
• a front side illuminated image, which is an image of the package taken by the camera device with the front side illuminating device being ON, and
• a back side illuminated image, which is an image of the package taken by the camera device with the back side illuminating device being ON;
• and
• wherein the control device executes the medicament information detection process by performing the following steps:
• a medicament candidate area extraction step comprising extracting a dark colored area in the back side illuminated image as a medicament candidate area A where the medicament is assumed to be present,
• a print candidate area extraction step comprising extracting an area containing a print on the package based on the front side illuminated image as a print candidate area B,
• a print area identification step comprising identifying an area corresponding to the print contained in the print candidate area B as a print area C based on a brightness distribution of the back side illuminated image, and
• a medicament area identification step comprising identifying a medicament area X by subtracting the print area C from the medicament candidate area A.
